As far as I can tell there are no monitoring of monitorable I need to know what is the best way to manage a sword in Godot 3d, detecting the hit and get the position of hit. Just make sure to disable monitoring property of the area using the script, that way it'll turn "off" your Area2D collision checks and each time I think you can use collision_layer to distinguish your walls from others physics objects. body can be a PhysicsBody2D or a TileMap. move_and_collide, it stops if it d KinematicCollision3D — Godot Engine (4. Make an area2d node and instead of collision shape as the child, put the spike tilemap instead. , Utilisation d'un maillage convexe ou concave comme forme de collision. Matrix components and the Identity matrix; ※: Barring continuous collision detection (which is only available for RigidBody(2D) in Godot, btw). 👤 Asked By sprengerjan So i created a Tilemap with two different Tilesets. This guide explains: The types of collision shapes available in 3D in Godot. Have your wall tiles set up with collission shapes in the To detect a collision in Godot you use Collision Objects, that is one of these: Area (or Area2D) StaticBody (or StaticBody2D) RigidBody (or RigidBody2D) KinematicBody (or By the end of this article, you'll have a solid understanding of how to implement efficient collision detection in Godot.
